WHAT IT DOES

What delete_contact does on MCP Google Contacts Server

AI agents call delete_contact to permanently remove resources in MCP Google Contacts Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_contact is rated Critical

This tool permanently removes contact records from Google Contacts without the ability to undo the operation through normal means. Deletion is irreversible and represents a loss of data. While not as critical as financial or organizational-level destructive actions, deleting user contacts has significant impact on data integrity and user operations.

From the tool's definition Tool name is 'delete_contact' and description states 'Delete a contact by resource name' - the verb 'Delete' explicitly indicates irreversible data removal.
